A novel path to lanthanide complexes of aromatic carboxylates controlled by the hydrolysis of the corresponding aromatic carboxylate ester has been discovered. A dimeric samarium complex of pyridine-3-carboxylate (NIC) has been obtained using triethyl pyridine-3-carboxylate (MNIC) as the starting ligand. With the hydrolysis of MNIC to NIC in the presence of sodium hydroxide, samarium ions coordinate to HNIC to form [Sm(NIC)(3)(H2O)(2)](2). X-ray analysis reveals the dimeric structure formed through bridging oxygen atoms of carboxylate groups. The complex crystallizes in the monoclinic space group P2(1)/c with a = 9.669(3), b = 11.807(3), c = 17.512(5) angstrom, beta = 92.361(3) V = 1997.3(10) angstrom(3), D-c = 1.838 Mg m(-3) Z = 2, R-1 = 0.0225. The complex exhibits strong luminescence.
